SARA, Amsterdam, The Netherlands At the Pittsburgh Supercomputing Center, we are using locally developed software to record animations on a SONY LVR5000 video disc. Most of our images are in the Computer Graphics Metafile (CGM) format. To render the CGM files, we use GPLOT, the CGM interpreter. GPLOT's IRIS device driver (igl) renders the image, and recording is done on the Sony Laser Videodisk Recorder (LVR-5000) using Gplot's lvr controller. GPLOT's LVR controller selects the first available blank space on the laser video disc to start laying down a series of CGM images. In addition to the video area on disk, there is also a user data area. For each GPLOT session, a user data frame is written. The frame contains a datastamp, the CGM file name, user name, number of copies per CGM image, and video start and end frame numbers. A disc need's to be initialized before any frames can be layed down on it. The software "lvr_do" will initialize a disk. It can also be used to perform playback, search and other operations on the video disc. GPLOT and LVR_DO software are available from calpe.psc.edu (128.182.62.148). ftp in as user anonymous (any password). cd to pub/gplot, and get the gplot.tar file. Un-tar it on the IRIS, and edit the Makefile before building Gplot. cd to pub/lvr, and get lvrdo.tar and rs170.c. Before starting laying down frames, you will need to type "rs170 on" on the IRIS. Un-tar the tar file on the IRIS, and make lvr_do. Please send me mail if you pick up a copy of this software. -Anjana Kar Pittsburgh Supercomputing Center kar@a.psc.edu
